I just love sharing cleaning tips and hacks with you! Today I’m sharing how to easily clean window sills and tracks! I know my window sills are often neglected and it’s not just me. I think every house we have moved into the window sills still needed to be cleaned. They collect dirt, bugs, and bits of leaves, so they get gunked up and nasty pretty quickly.

What are window sills and window tracks?

Before we get to cleaning, let me share with you the difference between window sills and window tracks because people often get them confused. The window sill is the part of the window where the glass rests when it’s closed. It’s not the part of the window that juts inside your house where you can put plants and things. That part is called the apron. Window tracks are the actual track where your window slides up and down.

How often to clean window sills?

If you’re following my plan for zone cleaning, I always include windows. My zone cleaning rotation has you deep cleaning certain rooms every two months. You don’t have to clean your window sills and tracks that often. I do suggest you clean them twice a year. Once in the fall, and once in the spring.

How to clean window tracks?

Let’s start with the window tracks since any debris in the tracks will fall down into the window sill. I use my vacuum with the crevice attachment and suck all the dirt and debris out of the tracks. Next, I take a homemade cleaner spray mixture with one cup water, one cup rubbing alcohol, and a squirt of dish soap and spray the tracks. 

After the spray has set for a couple of minutes, I wipe down the tracks. Then, I wrap a butter knife with a paper towel and use that tool to scrape out the window tracks. A toothbrush can also be helpful for getting into tight spots. Then, I just wipe until the mess is gone.

How to clean window sills inside?

Once the window tracks are clean I move to the window sills. I follow the same procedure. First, I vacuum all loose debris. Then I spray the surface of the window sill with an all purpose cleaner. I use a toothbrush to loosen the dirt and grime in the window sill, and then I wipe the mess away. You can use paper towels or old cleaning rags to do the dirty work of wiping away the mess.

How to clean window sills with baking soda?

You can also use baking soda to scrub your window sills. Once you’ve vacuumed your window sill, sprinkle baking soda all along the sill, then spray vinegar on the baking soda and let it sit. Make sure you’re getting a good, bubbly reaction.

If you have a wet vac you can vacuum the mess away after you’ve scrubbed and loosened everything. Once you remove all of the vinegar/baking soda/grime, you would finish with a little all purpose cleaner and wipe the window sill clean.
